摘　　要：通过对西南地区千枚岩弃料压实土进行路用特性试验,可知千枚岩破碎结构块料在压实后颗粒级配变化中起主导作用;千枚岩混合料容易压实,但压实后具有高水平的遇水变形特性;千枚岩弃料是一种高分散性的土料,压实后遇水极易崩解。基于以上特性,在用千枚岩弃料作为路堤填方时要加以防范和进一步研究。This paper carried out the experimental study on road engineering property of compaction phyllite material abandoning in the southwest area of China.The experiment results indicated that the broken structure phyllite pieces played a leading role in changes of particle gradation of compacted material;and the phyllite mixture was easy to be compacted,but the compaction had noteworthy deformation characteristics.The phyllite material abandoning had highly decentralized characteristics and was extremely collapsed in water.Based on the above characteristics,the effective measures should be carried out,when phyllite material abandoning was to be used to embankment fill and the characteristics should be studied further.
